This study considers the Romanian exosomatic metabolism for some <strong>of</strong> the lower level sectors <strong>of</strong> thepaid work compartment (levels n-3 <strong>and</strong> n-4). For level n-3, we consider groups <strong>of</strong> industries, mining <strong>and</strong>energy, manufacture <strong>and</strong> building, <strong>and</strong> transport; subsequently, for level n-4, manufacture <strong>and</strong> buildingsector is split into individual industries. Details regarding the microeconomic evolution are provided forsome industries sorted by the intensity <strong>of</strong> their exosomatic metabolism.The study is organized as follows: section 2 presents, using graphs, level n-3 <strong>and</strong> n-4 results forMuSIASEM exosomatic metabolic rate; section 3 presents data processing details for the three types <strong>of</strong>data: energy, hours <strong>of</strong> work in each paid-work activity, <strong>and</strong> gross domestic product (very importantdetails when the economy is disaggregated down to level n-4); finally, section 4 concludes.2. Energy metabolism Intensity Results for levels n-3 <strong>and</strong> n -4The evolution <strong>of</strong> the energy metabolism intensity (exosomatic metabolic rate) for different groups <strong>of</strong>industries (level n-3) <strong>and</strong> industries (level n-4) are discussed. For level n-3 (Figure 1) we consider thefollowing subsectors for the productive sector: mining <strong>and</strong> energy (MiE) <strong>and</strong> manufacture <strong>and</strong> building(MaB). Similarly for the services <strong>and</strong> government sector we consider as subsectors: transport, publicadministration <strong>and</strong> other sectors. Each <strong>of</strong> these subsectors (except for public administration <strong>and</strong> othersectors) can be split further at level n-4 (Figures 2 to 5). Structural changes in each economic sector canbe related to metabolic variations <strong>and</strong> this section will provide microeconomic details for certainindustries to support this statement.Figure 1.Figure 2 depicts the EMR for the Manufacture <strong>and</strong> Building sector split first between theManufacture sub-sector <strong>and</strong> Building industry. It is noticeable the similar pattern between 1999 <strong>and</strong>2002 <strong>and</strong> the opposite behavior <strong>of</strong> energy metabolism afterwards; this behavior requires the discussion<strong>of</strong> level n-4 manufacture industries.69
